Description

This is the DIY-EFI SpeedySim.
A product to allow you to test the inputs and outputs of your ECU.
It was developed to with the Speeduino ECU project in mind, so has a 40 pin connector which will allow direct plug and play with the 0.4 series.
For all other Speeduino designs (and many other standalone ECUs) you can use the 3 headers via the supplied cables or dupont jumpers to connect to your inputs and outputs.

SpeedySim has an onboard Arduino compatible Nano which runs Ardu-Stim software to allow the creation of Crank and Cam patterns.
The default pattern is 36-1 Crank only and this is variable using the TPS/RPM potentiometer.

There are 6 potentiometers in total for input simulation.

TPS (Also varies RPM)

There are 12 LEDs on board for output testing.
4 for injector channels, 4 for ignition channels and 4 for low side driver channels.

Note: The unit will come fully assembled with the exception of the 40 pin header, so the size is smaller id not using with a 0.4 Speeduino board.This will be included in the package and soldering to the board will be down to the user.
